Effects of Mg on reaction process

morphology and relative density of reaction products in Mg-Al-Ti system were investigated

and the Mg matrix composites were successfully prepared.The results reveal that the Al3Ti phase is dominant in reaction products in Mg-Al-Ti system.Mg element plays a role in decreasing initial temperature and in extending initial time of synthesized reaction of Mg-Al-Ti system.With increasing in Mg content

relative density of reaction products is obviously improved

where the relative density reaches 97.0% with 75% Mg content.In addition

created Al3Ti particles exhibiting round morphology and uniform distribution are refined with Mg addition.As a result

Al3Ti particle reinforced Mg matrix composites with 1

3

μm of Al3Ti which is relatively uniformly distributed in Mg matrix can be successfully fabricated by in-situ reaction synthesis in Mg-Al-Ti system.
